O2 sensor help please

[wikkid]

2003 XLT 4.0. Code p2270 indicates bad sensor passenger side. I only see 2 ox sensors on this truck, when i read threads that says it has 4. I see no sensors at all after the cat. Single muffler, single exhaust. Am i missing something.

Where are the downstream sensors?
thanks

Right after the first cat (one on each side) and one right before the first cat (one each side).

Yep, They're only about 24" apart.

OP, you need to look further ahead on the exhaust towards the engine.

If you need a pic let me know as my exhaust is currently on the ground.
